hi all needto put a question out here.... "ol futile" has a trimatic 3 speed in it round 100kms its revs are around 2800.. an at 110 are 3080.... if i could put a 4 speed auto in..would my ratios be more better reduced or not much variation ??? open to suggestion of autos to use, pitfalls etc too cheers in advance, yor collective thoughts are much appreciated as always .. skippy :-) :-)
-
So it's got a 3.08 diff in it then Might be a bit stiff for the old 6 cylinder with 4 speed auto as it will take about 1000 rpm off it in top gear & it will be constantly changing from 3rd to top A 3.45 diff would be better
-
sorry reid didnt mention it has a 253 in it dedicated to gas think ben IDed the diff as a bedford with a highway centre in it?? from memory ..
-
That's cool Skipp Yeah just wack the OD Auto in it & your revs will drop to 1800 at 100 ks just like my v8 falcon PERFECT
-
cheers reid ;)....uum wots an OD auto ??? ??? ;D ;D
-
OD = overdrive. 3rd is 1:1 and 4th is less.
-
i knew that!!.. ::) ::) ::) ;D ;D thanks guys know of any particular ones that go straight in or do i have to go an adapter plate ?? cheers

I have a vn t700 on the 2fluffy3 with an adaptor plate think it came from Castelmain rod shop. Needs to be a 5 liter auto because the v6 belhousing is too small. The vn t700 has the mechanical overdrive and locking converter and kickdown cable so you can hold it in gears. Best mod ever done but just be careful on the free way as it tends to hit the 110 and 120 a bit easier than it used too.

mate, you need an adaptor plate. Only problem is that a T700 behind the inline 6 still means that you have to cut the floor to fit it.
I've got a spare in T700 in the shed if anyone wants it.

Neil (Willo),
Skippy's is a 253 bent 8. Therefore the question is.... what difference is there in the tranny housing bolt pattern between a 253 and a post VN V8 T700. ???
Sorry if I stole anybody's thunder. ;D ;D ;D

a trimatic bell housing will be flat across the top, and the 304 bellhousing has a pointed top. and I believe some of the bolt holes are totally in the wrong spot.
-
ok these bell housings are not the right one for the gearbox size but they clearly show the difference in the engine side of the bell housing.
have labelled them as
304 = VN V8 onwards (might include VL also)
308 = 253/308 older motors.

thanks for your input guys.... kinda thought an adapter plate would be needed.... its more the crossmember lining up n stuff like tailshaft lengths , imagine i would have to change yoke which isnt hard ... ( famous last words!! ). ;D ... whats th go with your 700 willo??
-
T700 has the same spline yoke as a trimatic, but it will be a fair bit longer so tailshaft and gearbox crossmember are going to be an issue.
if you are going to do it, I'd recommend getting a commodore tailshaft made to the right length, the uni joints and yoke are a fairly strong unit and probably going to be easier to get parts for down the track if you ever need to.

I bought it to fit behind the inline 6. Came out of a running VP V6. Looks to have a record torque converter as it is that pretty green/blue colour that they paint them when they reco them. Never got around to trying it out though
Am open to offers as I am just tripping over it and I am just over it :D :D
Will swap for beddie bits (or a carton) whatever takes your fancy. ::)
PM me and we'll talk but cannot ship as too big ;D
The V6 gearbox fitted up to the original mount Trimatic and beddie cross member if that's any help
